Background
There is limited data on access to radiotherapy services for CARICOM nations.
Methods
This was a descriptive mixed-methods observational study which used data collected via survey from staff working in Radiation Oncology in 14 CARICOM countries. Benchmark recommendations from the International Atomic Energy Agency were compared to existing numbers. The Directory of Radiotherapy Centers, World Bank, and Global Cancer Observatory databases were all accessed to provide information on radiotherapy machines in the region, population statistics, and cancer incidence data respectively. Both population and cancer incidence-based analyses were undertaken to facilitate an exhaustive review.
Results
Radiotherapy machines were present in only 50% of the countries. Brachytherapy services were performed in only six countries (42.9%).
There were a total of 15 external beam machines, 22 radiation oncologists, 22 medical physicists, and 60 radiation therapists across all nations.
Utilizing patient-based data, the requirement for machines, radiation oncologists, medical physicists, and radiation therapists was 40, 66, 44, and 106, respectively. Only four (28.6%) countries had sufficient radiation oncologists. Five (35.7%) countries had enough medical physicists and radiation therapists.
Utilizing population-based data, the necessary number of machines, radiation oncologists, and medical physicists was 105, 186, and 96 respectively. Only one county (7.1%) had an adequate number of radiation oncologists. The number of medical physicists was sufficient in just three countries (21.4%). There were no International Atomic Energy Agency population guidelines for assessing radiation therapists.
A lower economic index was associated with a larger patient/population to machine ratio. Consequentially, Haiti had the most significant challenge with staffing and equipment requirements, when compared to all other countries, regardless of the evaluative criteria. Depending on the mode of assessment, Haiti’s individual needs accounted for 37.5% (patient-based) to 59.0% (population-based) of required machines, 40.1% (patient-based) to 59.7% (population-based) of needed radiation oncologists, 38.6% (patient-based) to 58.3% (population-based) of medical physicists, and 42.5% (patient-based) of radiation therapists.
Conclusion
There are severe deficiencies in radiotherapy services among CARICOM nations. Regardless of the method of comparative analysis, the current allocation of equipment and staffing scarcely meets 50% of regional requirements.
