Multidisciplinary first-day consultation accelerates diagnostic procedures and throughput times of patients in a head-and-neck cancer care pathway, a mixed method study
BMC Health Services Research volume 18, Article number: 820 (2018)
Head and neck cancers are fast growing tumours that are complex to diagnose and treat. Multidisciplinary input into organization and logistics is critical to start treatment without delay. A multidisciplinary first-day consultation (MFDC) was introduced to reduce throughput times for patients suffering from head and neck cancer in the care pathway. In this mixed method study we evaluated the effects of introducing the MFDC on throughput times, number of patient hospital visits and compliance to the Dutch standard to start treatment within 30 calendar-days.
Data regarding ‘days needed for referral’, ‘days needed for diagnostic procedures’, ‘days to start first treatment’, and ‘number of hospital visits’ (process indicators) were retrieved from the medical records and analysed before and after implementation of the MFDC (before implementation: 2007 (n = 21), and after 2008 (n = 20), 2010 (n = 24) and 2013 (n = 24)). We used semi-structured interviews with medical specialists to explore a sample of outliers.
Comparing 2007 and 2008 data (before and after MFDC implementation), days needed for diagnostic procedures and to start first treatment reduced with 8 days, the number of hospital visits reduced with 1.5 visit on average. The percentage of new patients treated within the Dutch standard of 30 calendar-days after intake increased from 52 to 83%.
The reduction in days needed for diagnostic procedures was sustainable. Days needed to start treatment increased in 2013. Semi-structured interviews revealed that this delay could be attributed to new treatment modalities, patients needed more time to carefully consider their treatment options or professionals needed extra preparation time for organisation of more complex treatment due to early communication on diagnostic procedures to be performed.
A MFDC is efficient and benefits patients. We showed that the MFDC implementation in the care pathway had a positive effect on efficiency in the care pathway. As a consequence, the extra efforts of four specialist disciplines, a nurse practitioner, and a coordinating nurse seeing the patient together during intake, were justified. Start treatment times increased as a result of new treatment modalities that needed more time for preparation.
The tumours in the head or neck region (nasal cavity, sinuses, lips, mouth, salivary glands, throat, or larynx) are fast growing tumours. This means that a long interval between the moment of referral and the start of the primary treatment (surgery, radiotherapy and/or chemotherapy) can lead to upstaging of the tumour with less chance on cure . Because of the complexity of the diagnostic procedures and therapeutic modalities, head and neck cancer care is centralized in special multidisciplinary head and neck cancer centres . Although the patient’s prognosis is determined by tumour stage, throughput time, defined as ‘day from first visit to day of start of treatment’ should be kept as short as possible [3, 4]. According to the Dutch Cooperative Head & Neck Group  treatment should start within 30 calendar-days after intake for 80% of new patients.
Until September 2007, the intake of head and neck patients at the University Medical Center Groningen (UMCG) was performed by the Department of Oral and Maxillofacial Surgery (OMS) and the Department of Ear, Nose & Throat (ENT), the front offices for the multidisciplinary head and neck centre. On the day of intake, the specialists or the nurse practitioner of the gate departments planned the diagnostic procedures, and two weeks after that, the diagnosis and treatment plan were discussed in the multidisciplinary meeting. In the meantime the involved supportive paramedical specialists, such as the dental team (special care dentist, oral hygienist), speech therapists, dieticians, and medical social workers, were consulted prior to the multidisciplinary meeting. This meeting was the first opportunity for a multidisciplinary discussion in the care pathway about treatment, based on written history, physical examination, laboratory data, and imaging. The patient was not present during the meeting.
In the Netherlands, the number of head and neck cancer cases increased between 1989 and 2016  from 1934 to 2995 cases which is an increase of 55%. The highest increase is seen for patients over 75 years with 88% followed by the age group 60–74 years with 80% (Table 1). This increase and limited resources were reasons to improve the efficiency of diagnostics and treatment for patients and because the performance of the centre on throughput time was poor in 2007 (only 52% of patients started their treatment within the 30-day standard), the centre decided to implement a multidisciplinary first-day consultation (MFDC) to reduce the time to start treatment.
Whilst care pathways are organized with multidisciplinary patient meetings (MPM), but as evidence based guidelines are accepted to organize care, the added value of each MPM still should be proven . Brunner et al. support this view in 2015 by explaining that the last 30 years multidisciplinary team meetings have become an essential component of tertiary-level decision-making in the treatment of malignancy . It seems self-evident that the variety of specialist team members with their combined knowledge and expertise improve decision making and therefore a MPM is often described in guidelines as a structure indicator.
The research question is: what are the effects of the MFDC implementation on efficiency of the care pathway, measured as process indicators throughput times (referral, diagnostic procedures and start treatment) and number of hospital visits (Fig. 1).
The MFDC was introduced in 2007 in the head and neck cancer care pathway using an ‘8-step method’ [9, 10]. The method compares the current with the desired situation to formulate improvement measures and realise sustainable change.
While the intake in the morning by the department of OMS and the department of ENT remained the same, the MFDC in the afternoon of the same day served as an extra effort among the two front office departments OMS and ENT and the department Radiotherapy. The four contributing specialities are ENT, Radiotherapy, OMS and the Special Dental Care. Special Dental Care is a sub-department within the Department OMS. The MFDC aims to provide a preliminary diagnostic plan, with multidisciplinary agreement, stating the diagnostic procedures to be performed, so intake for treatment modalities could start as soon as possible. The patient is informed on his or her diagnostic plan at the end of the day.
We applied a mixed method study [11, 12] combining statistical results and interviews. Firstly in search for process indicators for care pathway management we evaluated throughput times and number of hospital visits, secondly we performed semi-structured interviews of involved specialists of core departments to explore outliers in throughput times until data-saturation was reached.
The MFDC started in August 2007.
Four data sets were extracted, one data set of consecutive patients who were referred at least four months before the start of the MFDC (from April 2007 backwards), one data set of consecutive patients referred four months after the implementation of the MFDC (from January 2008 onwards) to compare immediate effects of MFDC. Two more datasets were extracted to analyse sustainability of the improvement over the five years after the implementation of the MFDC, one set of consecutive patients from January 2010 onwards and one set from January 2013 onwards.
Data of patients were included if they were 18 years of age and older, who had been curatively treated for a primary carcinoma of lips, oral cavity, oropharynx, nasopharynx, hypopharynx, or larynx (ICD(O) coding C00 through C14, C30 through C32) . Data were excluded if patients were treated for an unknown primary tumour (C80), a second primary tumour in the head or neck region or if a recurrent or residual tumour was diagnosed.
Process indicators and study design
The Dutch Cooperative Head & Neck Group developed the standard of ‘80% of the patients with a head and neck tumour start their primary treatment within 30 calendar-days from day of intake’, together with maximum throughput time for access to consultation and start treatment [2, 4]. For the evaluation of the effects of the implementation of the MFDC, the process indicators throughput times and number of hospital visits were used [1, 14,15,16]. We distinguished three different throughput times: the time to gain access to the first oncology consultation (access first consultation); the time to finish the diagnostic procedures, including the treatment plan (diagnostic procedures); and the time to start the first treatment (start first treatment). The throughput times ‘access first consultation’, ‘diagnostic procedures’ and ‘start first treatment’ were measured from the day the patients had their first oncology consultation in either one of the front offices of the centre. In the pre and post intervention situation in the centre, the consultation or intake was done once a week, independent of the number of patients referred (Fig. 1).
The first author registered the relevant data in a clinical registration form from electronic and written medical records. The last author checked the registrations of the medical records.
Our primary outcome measure was the change in the throughput time to start the first treatment as a result of the intervention of implementing the MFDC. Initially the sample size was set at about 20 patient records in each period (2007 and 2008) as a starting point to evaluate management of the care pathway over the years. Based on an analysis of these samples we would determine the definitive sample size. However in the analysis significant differences were found in throughput times hence data acquisition regarding 2007 and 2008 was not continued. Additionally to analyse sustainability of data, records of 24 patients from 2010 and 24 from 2013 were used. Statistical analysis was performed using SPSS 23.0 for Windows software.
Analysis of variance was applied to outcome variables throughput time (referral, diagnostic procedures, start first treatment) and number of hospital visits (total, from intake to diagnostic procedures complete, from diagnostic procedures complete to start treatment), ‘age at start treatment’. Because samples were small and assumptions were not met, biased corrected bootstrapping (2000 samples) was applied . The exact chi-square test was used to analyse differences in descriptive variables between the groups, regarding gender, tumour localization and tumour size, and compliance to the Dutch 30-day standard.
In all analyses, statistical significance was set at the 5% level.
Semi-structured interviews were used to explore reasons for non-compliance to the Dutch 30-day standard for starting the first treatment. Therefore the cutting point for ‘outliers’ chosen was defined as ‘longer than 37 days to start treatment’ (years 2008, 2010 and 2013); reflecting non-compliance to the Dutch 30-day standard and a (patient) delay of one week; for example if the first opportunity for outpatient clinic was skipped, either by the patient or for another reason.
We used the outlier cases to start the semi-structured interviews with one representative of each of the four departments that work together in the care pathway to give primary treatment (ENT, OMS, Radiotherapy and Medical Oncology). Prior to the interview the specialists were given the medical records of the outlier(s) to enhance recalling the case. Each semi-structured interview with a specialist started after getting verbal informed consent of the interviewees by providing them with information about the outliers. The interviewer (first author) then guided the interview using a short topic list including ‘cause of the delay’ and ‘perceived possibilities for change or improvement in logistics or of the care pathway’. The topics were introduced in a flexible way, and the interviews took the form of natural conversations.
The interviews were audio recorded and field notes were taken. Verbal transcripts of the interviews were made with the transcription program F4. The interviews lasted from 25 to 40 min. Quotations, related to throughput time or number of hospital visits, or improvement of the care pathway, were numbered in chronology of the interview. The first stage of the inductive analysis of interviews involved the last author and third author, in an open, initial coding procedure that resulted in a list of codes corresponding closely to the text fragments extracted from the four interviews. The codes were placed in a coding tree with major and minor themes in relation to management of the care pathway (Table 4) . Any disagreements about the codes were discussed between the coders and the first author .
In total 89 medical records were included in the study: 21 in the ‘pre MFDC group, year 2007’ and 68 in the ‘post MFDC group, year 2008-2010-2013’ (Table 2). Two-thirds of the groups were men, with a mean age of 66 years. The tumours were located in the oral cavity (tongue, gums or floor of mouth), the salivary glands, oropharynx, nasopharynx, hypopharynx, or larynx. The primary tumour classification ranged from T1 to T4 . We found no significant differences between the pre MFDC group and the post MFDC group in patient and tumour characteristics.
Throughput times for the diagnostic procedures and start treatment decreased significantly, with an average of eight days, after the implementation of the MFDC (comparison between 2007 and 2008) through the extra effort of the four specialist disciplines while no increase in personnel capacity was possible in the care pathway. Time to gain access to the first oncology consultation did not change significantly (Fig. 2 and Table 3).
The number of hospital visits during the diagnostic phase reduced significantly with one visit (p < .032) after the implementation of the MFDC (Table 3). Furthermore we analysed hospital visits during the diagnostic phase and from diagnosis to start treatment; for 2013 we saw an increase for hospital visits during the diagnostic procedures and an increase in the total number of hospital visits (Table 3).
Before implementation of the multidisciplinary first-day consultation, treatment started for 52% of new patients within 30 calendar-days after the first consultation. After implementation of the multidisciplinary first-day consultation, this percentage increased significantly to 83% (p < .040). This percentage decreased again in 2010 and 2013. In 2013 waiting time to start treatment increased for all treating modalities, therefore outliers were analysed. In total, we defined 8 cases (12%) as ‘outlier’.
Qualitative analysis – Specialist interviews
The specialists spontaneously gave their view on the agreements in the care pathway and described changes in guidelines, such as new treating modalities that may have increased throughput time.
In some cases the different aspects of a quotation was scored separately (Table 4). The interviews gave in total 76 scores, 37 quotations that were coded with 19 codes. Quotations appear in the text in italic.
Analysing the interviews we learned that:
introduction of new cure modalities chemotherapy and chemo-radiation took more preparation time and more hospital visits, coded as: ‘Planning reconstruction costs extra time’.
‘Duration and severity of surgery is not only the dissection of the tumour, but also the reconstruction that is discussed in the reconstruction meeting, like an obturator or a flap.’
‘The treatment date is known [date], but clearly there were not enough slots in the ‘major surgery planning’ to treat this patient in time.’
specialists were not aware that throughput times were lengthening, because information on throughput times is not easily available in the electronic patient dossier, coded as: ‘No management information on throughput times in electronic patient dossier’.
‘The gate specialist department agreed that they were supposed to keep track of throughput times, although this agreement was not traceable in writing.’
‘Register more accurately the throughput time when time to start treatment is longer than the 30-day standard.’
‘BROC (database for oncology registration) is only meant for basic tumour registration, not for management information on quality indicators.’
One of the specialist departments tried to reduce throughput times by creating time slots at the imaging departments, coded as: ‘Waiting time Radiology or Nuclear Medicine (imaging)’.
‘The slots are for radiotherapy patients at the Nuclear Medicine and Radiology department, for which hopefully in the future more slots become available in order to get PET-CT planned earlier. This is a logistic matter, which means that the amount of patients that need imaging to fit in the available slots is variable, sometimes only 2 and sometimes up to 10 patients. Back then we had less slots available.’
Throughput times reduced again, but because slots at the imaging department were on consecutive days, rather than the same day, the number of hospital visits increased.
co-morbid patients or patient delay took more time than expected (in 2013 62% of all patients started their treatment within the Dutch 30-day standard), coded as ‘Co-morbid or complex patient’.
‘Madam is admitted to a nursing home and has a long history – co-morbidity.’
the interviewees saw opportunities for improvement of the care pathway, coded as: ‘More attention to cooperation between disciplines to combine patient appointments’.
‘Nowadays we do not wait for PEG-placement to start treatment. During admission for the first chemotherapy, a PEG-tube can be placed.’
Combining quantitative and qualitative results
Effects of the implementation of the MFDC diminished in 2013 mainly because of the use of newer treatment modalities such as primary radiotherapy and chemo-therapy (from 32.6 days in 2007 to 22.2 days in 2008, and 23.7 days in 2010 back to 29.3 days 2013 on average, Table 3). In some cases patients needed extra time due to personal circumstances, in other cases preparation of a more complex treatment took more time and more hospital visits than in 2008 and 2010.
Each specialist gave his or her view on improving management of the care pathway when asked, they mentioned: ‘planning that cannot be influenced, when slots are not available’, ‘access of management information’ and ‘definitions of medical registrations’.
We found that throughput times for diagnostic procedures and start treatment decreased considerably, with about eight days during the first years after MFDC implementation in 2007. The reduction in throughput times was a result of better logistics due to a multidisciplinary diagnostic plan, made during MFDC. There was no effect on referral times, because the MFDC is organized once a week. In 2008 the care pathway was in compliance with the Dutch national standard of 80% of new patients starting their treatment within 30 calendar-days after oncology intake. The patients visited the hospital approximately one time less, during the diagnostic phase. As a consequence of the introduction of the MFDC, the extra efforts of four specialist departments, a special care dentist, a nurse practitioner, and a coordinating nurse seeing the patient together during intake, were justified.
However when analysing sustainability through 2010 and 2013 we found that throughput times for diagnostic procedures were sustainable, but not for start treatment. Besides that the number of hospital visits for diagnostic procedures and hospital visits in total increased in 2013 (Table 3). From the outlier-evaluation we learned that there were four major themes in the coding tree: intake, diagnostic procedures and logistics, treatment and planning, and case management for diagnostic procedures and treatment. Complex treatment and co-morbid patients at intake took more time. Logistics and planning during the diagnostic phase were more difficult with complex treatment, more diagnostic or imaging needed to be planned and treatment with cooperation of different specialist departments were difficult to plan on the same day. Dental foci treatment can only be performed when the total treatment plan is finished, but slows down the process of planning for start treatment. New features as 3D-planning for surgery give better results , but increase time to start treatment. For patients that need the most complex procedures planned, case management for that individual patient, tracking and tracing for all disciplines, would be helpful to keep the throughput time at a minimum. In most of these cases management information was not available and the involved specialists were not aware that the throughput times increased. This shows the added value of the MFDC in reducing the time needed for the diagnostic procedures for complex care.
In support of the above Ouwens et al. demonstrated in 2007  and 2009  that integrated care for head and neck cancer patients results in an improvement of perceived quality of care by improving patient centeredness in organizational issues like reducing waiting times and medical-technical quality of the diagnostic equipment. According to the guideline, patients need a treatment plan delivered by a multidisciplinary team of a cancer centre and an evaluation of the execution of that treatment plan registered in the patient dossier. To follow those guidelines for head and neck cancer it is of utmost importance for management of cancer centres to have throughput time and amount of hospital visit information available at all times .
Coordination of the logistics diagnostic procedures is important to shorten the time until the start of treatment. Time slots for diagnostic procedures can help improve efficiency of the care pathway and start treatment earlier [10, 24, 25].
We think that in our study we have shown that the MFDC for head and neck patients is an added value: implementation improved efficiency (reduced throughput times and hospital visits) and compliance to the Dutch 30-day standard. Therefore, when management of logistics of the care pathway can be trusted for 80% of patients, specialists can use the multidisciplinary patient meetings to have collegial discussions on complex cases and keep focus on patient centeredness.
We decided to include patients in a certain time period around the intervention to reduce bias. The moment it was decided that the MFDC would start on a certain date, changes may occur in procedures and patient selection. After the implementation of the MFDC it is likely that there is a learning curve. Therefore we chose an eight-months period, four months before and four months after the implementation of the MFDC, in which no data was gathered.
To evaluate the MFDC implementation we chose throughput times as process indicators because they are often regarded as logistic management measures and used as a ‘benchmark’ for several purposes. Governmental bodies around the world try to compare their quality of oncological care with indicators such as necessary infrastructure and volume, and throughput time with other countries [20, 26,27,28,29,30]. However, direct relation between throughput times and outcome for head and neck cancer patients in our hospital is not proven. We chose to follow the Dutch standards that advice to use registrations on new patients with certain malignity only, that we called ‘with curative intent’. Our indicators for process efficiency (throughput times) were chosen in a framework for measuring quality by assessing elements of structures or processes with proven connections with key outcomes of interest [31,32,33,34]. A good quality or process indicator signals changes in quality and is registered in a reliable manner [14, 30]. Implementation of structural planning of diagnostic procedures for head and neck cancer patients was found to have a positive effect on throughput times: time slots as a logistic structure reduced the diagnostic phase for head and neck cancer patients . The structural planning of slots for diagnostic procedures are appreciated by patient associations and are reflected in their description of process indicators . Several studies have shown that clinical characteristics of patients and prognostic factors explain a relatively large part of the variation in outcomes, such as survival and quality of life, while quality-of-care indicators explain a much smaller part [36,37,38]. Monitoring the process of care in a clinical pathway in direct relation to assessment of quality of care is of major importance to benchmark complex care such as head and neck cancer, but is difficult to assess [2, 39,40,41].
We wanted to show with a small sample and a simple method to evaluate, the effect of an intervention in the care pathway on efficiency. The added value of the extra multidisciplinary patient meeting is proven. We think that the combination of process indicators throughput time and number of hospital visits can be used in a dashboard to help care pathway management to monitor and sustain the agreements made.
The results of this study show that a ‘simple’ intervention, such as the implementation of the MFDC, can improve throughput times directly, which in turn can help improve the perceived quality of care. Especially with complex, life-threatening diseases such as head and neck cancer, shortening of the pathways diagnostic procedure is important so that treatment can start as early as possible to give patients a better chance of survival [3, 23, 42, 43].
In case of low-volume, highly complex care such as head and neck cancer, patients are treated in a centre with large adherence area, about 11,400 km2 with a total of 2.3 million inhabitants for our centre. Because of travel distances, reducing hospital visits with one visit is a valuable contributor to patient comfort and cost reduction. A decrease of time of uncertainty about diagnosis, treatment and prognosis also reduces patient anxiety and increase patient satisfaction .
The reduction in throughput time was achieved mainly in the diagnostic phase of the care pathway. Although this study did not aim to improve a specific phase before start treatment, the time between the end of the diagnostic phase with the treatment plan and the start of the treatment has become relatively long. We recommend examining production agreements or slots for planning with medical support departments to further reduce the time to start treatment, thus reducing the risk of upstaging even more.
The reduction in throughput times was a result of better logistics due to a multidisciplinary diagnostic plan, made during MFDC. Management of the care pathway can use these indicators to stay focused on sustainable, seamless processes of care in a multidisciplinary setting [40, 44]. We would like the information needed for care pathway management to become available through our electronic patient dossier and in a dashboard, so that lengthening of throughput times could be detected before they become unacceptably high. In case of change in the described process indicator combination from agreed levels, the management should look for variation or deviation on the agreements on the care pathway (with best intentions made) that could influence future patient outcomes.
We showed that the MFDC implementation in the care pathway had a positive effect on efficiency in the care pathway. As a consequence, the extra efforts of four specialist departments, a special care dentist, a nurse practitioner, and a coordinating nurse seeing the patient together during intake, were justified. Start treatment times increased as a result of new treatment modalities that needed more time for preparation.
